Crysis 2 is running fine with a resolution of 1366*768 at hardcore with an average frame rate of 35..

I suppose you replaced the GPU from HD 5450 to 9800 GT? How did you reinstall drivers?

I'm reasonably sure you downgraded the GPU... MW3 also tends to be more memory bandwidth intensive, which has always been a strong suit of AMD/ATI cards compared to NVIDIA.

What.....?????
U r doubting that i downgraded my gpu...!!!!!!!!!! lol...i expected a better answer bro...for your kind information , even a greetings card in the PCI slot would be more powerful than an ati hd 5450.......lol
and in my older gpu, i used to get a frame rate of 4-5 in battlefield 3 on 800*600 at lowest graphics....
But now my 9800 GT is managing 35-45 at 1366*768 at ultra......see d difference man...!!!!!!!
And an ati hd 5450 has a total watse of 2 gbs of vram on it...it rarely uses more than 256 mb.......u can check at

Can my problem be related to direct x...?????

do you have any idea about the difference in memory bandwidths of these 2 cards???????
Hd 5450- 12.8 gb/sec
9800 GT - 57.6 gb/sec
i upgraded my gpu after a ton of research....so i'm sure of what i'm talking....
Now can u please provide a fix if u can...!!

my gpu usage msi afterburner while playing remains at 40-45%...
How can u all expect a game with such macabre graphics to be gpu intensive......???????
The graphics of mw3 is total crap..and just a bit better than IGI 2...lol

so is my gpu usage fine or abnormal..????

Can you check the CPU usage in task manager? There's your reason for lagging: for some reason your graphics card cannot use its full potential.

go into the game settings and turn shader warming off. (its in the first options menu if i remember correctly) if its on. if its already off try turning it on... if you cant find it there it may be in the cfg file in the user saves.
but off should work just some nvidia cards want it on for some reason...
go into the gfx settings and set the textures or what ever its called to native...
(1 of the boxes will display native as well as low medium and high.(i think its been a while since i played it sorry) either of these should fix your issue.

thankyou......thnxxx very much...!!
You duly came to my rescue..the shader warmer was in the config. file..and it was turned off
i turned it on and bang.....!!!
Max res. and max graphics...a stable frame rate of 65-80..wow...
Sigh of relief..
